DG413CY+ - 4-Channel SPST Analog Switch | Analog Devices
部品番号: DG413CY+ ✓ 生産中DG413CY+ 概要
An analog switch is an electronic semiconductor device that routes signals between circuit nodes under digital control. The DG413 belongs to the analog switch family within the broader interface IC and signal-routing hierarchy. Each of its four SPST channels connects one input terminal to one output terminal when enabled, allowing a system controller to select, isolate, or route external signals. The normally open configuration leaves the signal path disconnected until the appropriate control input is asserted.
The DG413CY+ is specified as a 4-channel, 1:1 SPST switch with 45 ohm on-resistance in a 16-SOIC package. The family is used in sample-and-hold circuits, test and measurement equipment, signal routing, and other applications requiring controlled analog connectivity. The manufacturer’s product information specifically highlights improved low on-resistance matching between switches and guaranteed on-resistance flatness over the signal range, helping preserve signal integrity when multiple channels must behave consistently.
The CY+ ordering code identifies the leaded 16-SOIC configuration, and the distributor results list both tube and tape-and-reel order variants under the DG413CY+ family. The product page identifies the DG413 family as production, so the listed DG413CY+ is presented as an active analog switch option. DG413CY+T is also listed by DigiKey and Arrow, while DG413DY+ is identified in comparison results as another 16-pin NSOIC member of the DG413 family.
For drop-in sourcing, verify the exact pinout, enable polarity, and package dimensions in the manufacturer datasheet before substituting a related ordering code. The verified data identifies the product as a 16-SOIC part, but it does not provide a complete pin table, control logic levels, channel leakage, charge injection, switching time, supply-voltage range, or temperature limits. Those parameters should be obtained from the DG413 manufacturer datasheet before final circuit approval.
This page combines the verified manufacturer and distributor information, same-package family alternatives, pricing references, and application-focused design guidance. It is intended to help engineers identify the correct DG413CY+ ordering code and distinguish it from related SOIC and TSSOP versions without assuming unreported electrical details.

主な用途
DG413CY+ の用途: 6 件s: Sample-and-Hold Signal Routing, Test and Measurement Equipment, Multichannel Sensor Acquisition, Battery-Powered Instrument Switching, Industrial Control Signal Routing, Audio and Analog Signal Path Switching.
Sample-and-Hold Signal Routing
The DG413CY+ fits sample-and-hold architectures because it provides four independent SPST, 1:1 signal paths controlled from a common logic interface. According to the Analog Devices product information, the DG413 family is explicitly used in sample-and-hold circuits and offers low on-resistance matching between switches of 3 ohm maximum. Matching helps limit channel-to-channel gain variation when the same source is routed through different paths. Its 45 ohm nominal on-resistance should be included in acquisition-path error and settling calculations, while charge injection and switching time remain [DATA_NEEDED]. Before implementation, verify control polarity, pin assignment, supply requirements, and acquisition timing against the DG413 manufacturer datasheet.
おすすめ
Test and Measurement Equipment
DG413CY+ is appropriate for bench and automated test systems that must route one source to a selected measurement channel under software control. The four independently controlled SPST switches reduce the number of separate discrete relays needed for simple point-to-point routing, and the verified 16-SOIC package supports conventional surface-mount PCB assembly. The manufacturer’s DG413 family information identifies test and measurement among its uses and specifies on-resistance matching of 3 ohm maximum and flatness of 4 ohm maximum. Designers should still account for the 45 ohm on-resistance when calculating divider ratios, and should obtain leakage, bandwidth, switching-time, and charge-injection data before setting precision or high-speed test limits.
おすすめ
Multichannel Sensor Acquisition
The DG413CY+ can select among several sensor or conditioning inputs in a compact multichannel acquisition system. Four 1:1 SPST channels provide straightforward source isolation and routing, while the 45 ohm on-resistance is an important factor when driving high-impedance sensor networks. The family-level matching and flatness specifications help maintain more consistent behavior across channels than an unspecified generic switch. For low-level sensor signals, verify leakage current, off isolation, noise, and charge injection because those values are not present in the supplied web excerpts. The control outputs of the host microcontroller should also be checked for voltage compatibility, and the exact enable polarity must be confirmed from the manufacturer pin table.
おすすめ
Battery-Powered Instrument Switching
DG413CY+ is useful in portable instruments where analog inputs must be disconnected to reduce loading, leakage pathways, or unwanted signal paths. Its four-channel SPST topology allows a controller to isolate inactive sensor, keypad, or calibration networks without requiring four separate discrete switch packages. The verified distributor data does not provide supply voltage, quiescent current, or power-consumption figures, so battery-life impact must be evaluated from the official datasheet rather than estimated from the 45 ohm on-resistance. Designers should include the switch’s on-state resistance in sensor-loading calculations and confirm whether normally open behavior matches the instrument’s fail-safe requirements. Control-state timing during sleep and wake transitions also requires verification using the manufacturer timing data.
おすすめ
Industrial Control Signal Routing
The DG413CY+ can route control, feedback, or reference signals in an industrial controller when a compact four-channel analog switch is sufficient. The SPST configuration is particularly suitable for normally open isolation points, while the manufacturer’s guarantees for switch matching and on-resistance flatness support predictable behavior across nominally identical paths. The 16-SOIC package is easy to inspect and rework, making it practical for prototypes and serviceable control boards. Industrial suitability cannot be qualified from the supplied excerpts because operating temperature, supply range, and exact compliance fields are [DATA_NEEDED]. Before release, engineers should review isolation voltage, leakage, rated switching levels, and lifecycle documentation, then validate the selected analog signal’s amplitude and bandwidth against the manufacturer limits.
おすすめ
Audio and Analog Signal Path Switching
DG413CY+ can implement source selection in a compact analog audio or mixed-signal system where four SPST paths are required. Because the switch conducts in either direction, it may route a selected source toward downstream amplification or measurement circuitry. The verified 45 ohm on-resistance is manageable for many high-impedance audio paths, but it becomes important when driving low-impedance loads or forming precision passive networks. The family’s 3 ohm maximum matching and 4 ohm maximum flatness figures help limit channel-dependent response differences. Off-channel crosstalk, insertion loss, distortion, bandwidth, and switch-noise data are [DATA_NEEDED] and must be taken from the manufacturer datasheet before making a high-fidelity claim. Keep analog routing away from noisy digital return paths to minimize ground coupling.

設計ノート
Include the verified 45 ohm on-resistance in the complete signal-path calculation rather than treating the switch as ideal. For a resistive source and load, the switch contributes attenuation in addition to source impedance and load impedance. The DG413 family specification of 3 ohm maximum matching between switches and 4 ohm maximum flatness over the signal range can be used when evaluating channel-to-channel consistency. Exact insertion loss, bandwidth, off isolation, and distortion require values from the manufacturer datasheet.
Route switched analog signals away from digital control lines and high-current switching nodes to reduce capacitive and ground-coupled pickup. Place the DG413CY+ close to the signal source or receiving network when trace capacitance and resistance could materially affect the application. Maintain a continuous ground reference under the 16-SOIC device and follow the manufacturer’s recommended decoupling arrangement. The exact pin locations and exposed-connection requirements must be taken from the official DG413 pinout before layout signoff.
Do not substitute a related DG413 suffix solely from the family name. The verified excerpts identify DG413CY+ as 16-SOIC and DG413DY+ as 16-pin NSOIC, while DG413CUE+T is identified as TSSOP-16 and therefore is not a footprint-compatible replacement. Before ordering an alternative, compare the numbered pins, normally open behavior, enable polarity, logic thresholds, supply requirements, and electrical limits in the manufacturer datasheet.
コンプライアンス情報
The verified excerpts do not explicitly provide the required compliance declarations for DG413CY+. A third-party listing mentioning RoHS was not treated as authoritative manufacturer evidence.
